Doomsday Diesel Part 4 Setting Pinion Bearing Preload

While we were working on the wheel hubs, we called Frank Gilliland at South Bay Truck & 4x4 and made an appointment to have him set up the gears. He used a 3/4-inch-drive impact gun and a 36mm socket to compress the crush sleeve and set the pinion- bearing preload. As he got closer to the factory spec of 15 to 30 in-lb (for new bearings), he verified the pinion bearing drag with this torque meter.
